We were broken into twice a few years ago, (we were the first floor in a victorian conversion) and were offered a security assessment though can't remember if it was offered by the police or the council.

Either way, they recommended two locks on our flat door, including a 5 lever mortice lock, a London bar behind the door to prevent it being forced open and window locks.

Hope this helps, because this is a horrible thing to have to go through.
